TT MIXTURES FOR SPORTSGROUNDS

Turf managers maintaining the full range of sports areas will appreciate the extensive work carried out by the DLF Trifolium breeding team to produce cultivars offering high ratings for wear tolerance, sward density and tolerance of close mowing.

The mixture formulations following, and the varieties therein, take full advantage of these characteristics, providing the sports turf manager with assured sward performance.

STRI TRIAL ON THE EFFECTS OF DIFFERENT SEEDING RATES

ARE YOU APPLYING SUFFICIENT SEED TO CREATE THE DESIRED RESULT?

DLF Trifolium have recently commissioned the STRI to carry out an independent trial studying the effects of different seeding rates.

The trial was set up to examine the speed of recovery, over an 8 week period, of a heavily worn perennial ryegrass sward overseeded with a perennial ryegrass mixture sown at different seed rates.

An area of perennial ryegrass turf was intensively worn using a differential slip wear machine fitted with football stud rotors. The trial area was prepared using an Auto Seeder. Four passes were made over the area in four different directions to produce a fine tilth.

WEEK 3
ABOVE 75g/m2	STANDARD 25g/m2	CONTROL Control

• Very marked difference between seeding rates
• Greater grass cover and increased turf quality for highest seed rate
• All significantly better than standard (25g / m2) and half standard (12.5g / m2)
  
  
  
  

WEEK 5
ABOVE          75g/m2	STANDARD    25g/m2	CONTROL     Control

• Grass cover and visual turf quality very similar for highest seeding rates
• Higher seed rates significantly more grass cover and better visual turf quality than standard and half standard
• Significant benefit of overseeding on grass cover and visual turf quality 
  
  
  
  

WEEK 8
ABOVE 75g/m2	STANDARD    25g/m2	CONTROL     Control

• Differences between the extremes of seeding rate still apparent

CONCLUSION

Increasing overseeding rates during the renovation of worn perennial ryegrass turf dramatically increased the speed of establishment and turf quality of the sward. During the establishment phase there was a direct relationship between seed rate and turf quality.

The higher seed rates markedly reduced the time required to achieve a surface that would be deemed fit for use. The density and uniformity of sward produced at the end of the establishment phase was also improved by increasing the normal seed rates.
